Background technology
For yarn qualities monitoring, the way being usually taken under the current state of the art is：Horse after yarn production terminates
Upper implementation quality monitoring (such as and then carrying out after rotor spinner yarning position) or the step of operation after manufacturing
(such as by yarn during a bobbin turns around another bobbin) monitoring yarn qualities in rapid.Generally monitoring physics is joined here
Number or the measured value related to these parameters.Following known method such as can be adopted：By assessing yarn in a chain of command
On projection, analysis yarn rugosity or yarn fuzzability, thus infer yarn qualities.
In order to draw the reliable conclusion with regard to yarn qualities according to gathered measured value, need a reference value all the time,
Gathered measured value can be compared with this reference value.If the deviation between measured value and reference value is located at prespecified
It is believed that yarn qualities meet regulation within boundary.Patent document DE 102005017606A1 describes this yarn monitoring
Method.
Reference value determined before production process starts in the following manner：Within a certain period of time need monitoring measured value is entered
Row monitoring, and it is translated into reference value.
Above method is but taken to be unfavorable under the current state of the art, because reference value determination process consumption at the beginning
Time-consuming and existing defects.Especially when the reference value determination process starting mistake for some reason, lead to whole
The quality of the yarn of batch will be against regulation.
Content of the invention
So it is an object of the invention to provide a kind of method that on textile machinery yarn is entered with line quality monitoring, the method
It can be avoided that disadvantages mentioned above.In addition the present invention have also been devised a kind of textile machine being capable of respective quality monitoring.
Above-mentioned purpose will be completed by the method and textile machine that possess feature described in independent claims.
Yarn qualities monitoring method of the present invention has following characteristics：Proprietary according to one or more yarn,
The yarn parameter specifying before analysis selects reference value.
That is, reference value not recalculates when starting in yarn production or other operations, but in quality prison
Control just has been provided to textile machine before starting.
Suitable reference value is selected on the basis of above-mentioned parameter.Parameter can as explained in detail below, instead
Reflect the physical characteristics (fuzzability of such as yarn) of produced yarn, it would however also be possible to employ a yarn private code is as ginseng
Number.If produce a kind of yarn number be X, the twist be Y, fuzzability be Z cotton yarn, operator's (or control system) is just
Would appreciate that：Affiliated reference value 123 must be selected and provide it to textile machine.By this design, yarn production starts it
Front corresponding parameter value 123 will be read into or typing monitoring system.The measured value being monitored in process of production (such as reacts
Yarn rugosity) compared with described reference value.Even if change batch after it is also possible to reproduction have can reproduction characteristic yarn
Line, because for a certain yarn (can be defined by one or more parameter), providing all the time or select identical
Reference value.
Reference value selects to realize by above-mentioned yarn private code.But when selecting reference value it is also contemplated that many
Individual parameter such as yarn number, fuzzability or fibrous material used by spinning.
Reference value can be read in the centralized control unit of a textile machine, described centralized control unit is from unit
(such as weaving position or winding position) receives the measured value being individually determined, and it is compared with reference value respectively.Also may be used
To adopt following methods：Reference value is transmitted to each monitoring unit of corresponding units, and directly implements at corresponding units
Reference value-measured value compares.If the deviation detecting between measured value and (constituting corresponding ultimate value) reference value is excessive,
Pointed out or intervened the control system of corresponding units by sound and/or optical signalling, so as by monitored measured value or
The yam physical parameter that person affects measured value readjusts within allowed band.
Particularly advantageous way is corresponding reference value to be stored in a data base, when needed, that is, in quality monitoring
Read before beginning and transmit that (certain data base can also be the group of control system to textile machine control unit from data base
Become part, so can be with omitted data transmittance process).Reference value preferably with one of above-mentioned parameter or multiple exist join
System, so as to selecting suitable reference value based on parameter, or simplifies this selection course.
Following measures are particularly advantageous, using yarn rugosity as physical parameter, wherein can by a collection optical system with
The related measured value of this parameter, described optical system can analyze geometry when irradiating yarn by the produced projection of yarn.
A line-scan camera such as can be used, this video camera is carried out for the pixel of (or multiple side by side) pixel column
Analysis, to determine whether to recognize projection.This analysis provides the information with regard to passed through yarn width (certainly to take the photograph in positioning
It should be noted that pixel column can not be parallel to yarn y direction during camera).Yarn passes through one (to produce visible ray or invisible
Light) light source, and projection is produced on a corresponding chain of command.Project its space in one or more prescribed direction to prolong
Stretch, measure by video camera or other system and be scaled yarn rugosity.Yarn rugosity is above-mentioned physical parameter, and measured value
Can be by the current generated intensity of video camera according to projection geometries.Measured value can also detect a projection
Pixel quantity.
In addition following favourable ways can be adopted, select to consider yarn fuzzability, thread material, yarn during reference value
The line uniformity, yarn fibers fineness, yarn rigidity, yarn twist and/or yarn stress are as parameter.Can if by parameter
Identification yarn, thus being a certain yarn producing or carrying out other process by textile machine, selects one from data base
Individual or multiple affiliated reference values, then these parameters can use in principle.
In addition single value can be selected as reference value, wherein reference value is used as the rated value of measured value, and to measurement
Value or the value drawing from described measured value carry out numerical analysis, to determine the absolute deviation between these value and reference values.Can
Within a certain period of time positive and negative deviation is added up with (such as).If the aggregate value in certain time is higher or lower than corresponding
Ultimate value, then send warning or adjust selected textile machine monitored unit parameter (one on such as rotor spinner
The rotor speed of weaving position).
Following methods equally have advantage, and reference value exists as single value, obtains to measured value or from described measured value
The value going out is analyzed, with determine its numerical value whether be located at the minima of below reference value and the maximum on reference value it
Between.As long as measured value (or its numerical value) is located between minima and maximum, affiliated control system just will be considered that yarn qualities
Meet regulation.If exceeding correlation, illustrating to there is material and/or producing error.Therefore can by manual type or
Automatically intervention control system, so that each operational factor of Matching and modification textile machine.Warning can also be sent, to point out to operate
There is deviation in member.
Particularly advantageous way is that the first reference value defines the minima allowing, the maximum that the second reference value definition allows
Value, in quality monitoring process, whether inspection measurements or the value drawing from described measured value are located at minima and maximum
Between.In this case, the regulation of reference value is limited to select two ultimate values, and gathered measured value should be located at this two limit
Between value.If the yarn rugosity of (such as) known certain yarn (being defined by material, intensity, ductility etc. parameter)
Should be located between A and B, then numerical value A and B, using as reference value needed for the yarn with above-mentioned parameter, is stored in data base.As
Fruit needs to produce this yarn, then read described reference value from data base and transmit to corresponding control system or weaving loom
In each monitoring unit of tool.
Can also continuous acquisition and analysis measurement value.So-called " continuous " it can be understood as in practice continuous acquisition survey
Value is constantly to obtain the monitoring method of described measured value instantaneous value.But can also gather according to prespecified interval
And analytical data, this also belongs to " continuous " and carries out.Additionally statistical analysiss can be carried out to multiple monodromes of measured value, so that
(such as) one meansigma methods with regard to gathered measured value upper one minute of formation per minute, and by this meansigma methods compared with reference value
Relatively.
In addition it is also advantageous with absolute value form collection measured value.Lead to error and other values so can be eliminated
Relatedness.Value can be measured by plain mode between each yarn batch using this design to compare.Especially
May insure and realize following purpose：Production interval a few days or several weeks and during this period of time when two XY yarn batches
Have different qualities yarn AB produce on textile machinery or carry out other process when, the measured value of yarn XY remains able to
Carry out reliable comparison with the affiliated reference value being stored in data base.
Obtain reference value during reference measurement equally there is advantage, during reference measurement, acquisition is determined in advance
Benchmark yarn parameter and the benchmark yarn measured value related to described yam physical parameter, wherein with measured value or one
Based on the individual value being drawn by measured value, determine that one or more reference value, parameter and reference value are deposited with interrelated form
Storage is in data base.In other words, the data in data base generates in the following manner：The included yarn production phase in data base
Between measured value, during this yarn production or produce after the completion of obtain.Necessary parameter is also predefined, a kind of in the future most
Before yarn production process that may be close with benchmark yarn starts, choose reference value from data base by these parameters.Ginseng
Examine value to be associated with important yarn parameter in data base, thus ensureing to can be transferred through inputting related ginseng in any time in future
Number provides reference value by data base.
Particularly advantageous way is：When the maximum exceeding reference value or less than reference value minima when, preferably logical
Cross manual type and make regular check on yarn qualities, and reference value is re-defined according to quality examination result or keeps reference value not
Become.In other words, in data base, the reference value of storage not all keeps constant in all times.Such as can have ginseng for one kind
The yarn of number X, Y and Z stores a reference value A or minima and maximum B, C.If monitored measured value is less than minima
B, then, for control system and/or operator, show that yarn qualities are against regulation first.But if manually
Or by verifying attachment carried out yarn inspection (on textile machinery or an independent check position is checked) it was demonstrated that
Yarn qualities meet require for the yarn defined with parameter X, Y and Z it is possible in data base adjustment reference value A or
Minima and maximum B, C.This adjustment can be accomplished by：Change described value so that (with respect to original value position
Outside allowed band) measured value again be located between value B and C.Data base can constantly adjust, thus the ginseng once specifying
Examine value be not meant to exclude future adaptation adjustment (such as when yarn acceptor change yarn qualities require when, can basis
Need to reduce or increase the interval between minima and maximum).
If before to the monitoring of yarn implementation quality, taking out the reference value related to yarn parameter from data base and incite somebody to action
It is used for quality monitoring, will be particularly advantageous way.The yarn that preferably need to produce or need to be processed by textile machine in replacing
When, then execute readout.If textile machine downtime is longer, but carry out to the identical yarn of production or to identical yarn
The measured value that other process (such as turning around) and gather is absolute value, then do not need again to read reference value.
If by database purchase in textile machine control system or monitoring unit, it will particularly advantageous.Certainly
By database purchase in the place away from textile machine, can need to produce when changing or need to carry out other process yarn when,
Send data to textile machine manually or by corresponding network connection.In this case, a data base
The multiple stage textile machine being arranged on different production sites can be served.
Textile machine according to the present invention has following characteristics：It is designed with a control system, for specifying according to prior
One or more require monitoring yarn qualities.Refer to the description in context with regard to possible modification and advantage.This

First define measured value, later on textile machinery monitor yarn qualities when, gather this measured value and by its
As quality evaluation basis.Such as can be using a current signal being produced by video camera as measured value, and video camera can be surveyed
Determine yarn and accept the geometry of produced projection, especially width during light-illuminating.The numerical value of measured value in this case
Depending on yarn rugosity the spatially extended amount of yarn y direction (=perpendicular to), yarn rugosity is monitored.
After specifying measurement value, reference value will be defined for measured value.Reference value is when yarn qualities are intact, and measured value should have
Some numerical value.Certainly as supplementary or alternative it is also possible to pass through to allow the formal definition reference of minima and maximum
Value, when yarn qualities are intact, measured value should be located between defined minima and maximum.
In order to when producing certain yarn or this yarn being carried out with other process by textile machine, can be from comprising to join
Recall corresponding reference value in the data base examining value, reference value not only will be stored in data base as numerical value, also should with one or
The proprietary parameter of the multiple yarn of person sets up contact, can be corresponding with certain yarn by corresponding reference value at any time by these parameters.Make
Can be using code (such as alphanumeric code) or other proprietary parameter of yarn, such as thread material, yarn for parameter
The twist, yarn unit length, yarn fuzzability etc..Unique key point is that the reference value once specifying can also incited somebody to action
Sometime clearly to correspond to a certain yarn.
In other words, can be all the time to a certain yarn (such as a kind of fuzzability by solution of the present invention
For A, intensity be B, yarn number be the cotton yarn of C) carry out equivalent monitoring.Monitor this yarn if necessary, should be by affiliated reference
The corresponding yarn monitoring unit that value is transmitted to textile machine control system or is transferred to textile machine, so that monitoring benchmark
Point is identical all the time.If in addition carrying out parameter measurement in the form of measuring absolute value, not necessarily like logical under prior art state
Row way is the same, recalibrates monitoring unit in each replacing yarn.All the time yarn can be carried out reliably, especially may be used
Reproducibly quality-monitoring.
Fig. 2 illustrates and is choosing the step that can adopt when correct reference value or respective minimum value and maximum.
First must be by the parameter input database of monitored yarn.It is required that data base's offer is associated with parameter
Value.Reference value is transferred to textile machine control system or the corresponding yarn monitoring unit being transferred to textile machine, and conduct
Next the basis of carried out quality monitoring.
During monitoring, yarn measured value passes through the measured value representing measured value is measured with (preferably continuously measuring)
And obtain, and compared with reference value.If measured value is located at prespecified ultimate value (allow minima it is allowed to maximum)
In the range of, then explanation yarn qualities can accept.If measured value is less than or exceeds described permissible value, yarn qualities are described
Against regulation.Warning will be sent in this case, or tight after producing unqualified yarn when implementing yarn monitoring
Then intervene the control system of corresponding production unit.Purpose is to adjust manufacturing parameter, makes measured value be always positioned at described ultimate value
Within.
Fig. 3 illustrates a kind of method determining or adjusting reference value, and wherein M (y-axis) represents measured value, and t (x-axis) represents
Time.
If a certain yarn is still without reference to value R, first have to regulation and need to monitor the species of measured value M future (such as supervise
The line-scan camera signal of control yarn rugosity).Then start to gather measured value M, corresponding yarn passes through monitoring unit simultaneously
(t0：Start to gather measured value M).If yarn qualities meet regulation, in time point t1The measured value M (or one occurring in real time
The individual value being drawn by this measured value) it is defined as reference value R1, this value and the (fluffing of one or more typical yarn parameter
Degree, yarn number, yarn code and/or the other specification showing a certain yarn feature) set up contact, and it is stored in number
According in storehouse.If needing yarn implementing monitoring similar to characteristic again in a certain moment in the future, it will thus provide reference value R1, this ginseng
Examine value can transfer from data base at any time.
If (time point t for example in figure 3 during measured value changes over2), yarn monitoring display measurement
Value M is less than minimum M i allowing1(or：Maximum Ma1 beyond allowing), textile machine operator can implement yarn
Quality examination.If checking and showing that yarn qualities meet regulation all the time, reference value R will be from value R1It is corrected to value R2.After correction
